The International Committee of the Red Cross today released its 'interpretative guidance' on the concept of direct participation in hostilities as it applies to the law of armed conflict:
This much-awaited report will hopefully help to clarify a difficult topic. It has been discussed in case law (see the Kupreskic trial chamber decision at the International Criminal Tribunal for the former Yugoslavia) and academic writing. But when the ICRC makes a pronouncement, it has a lot of authority.
